Mechanochemical synthesis of nanoparticles by a dilution method: Determination of the particle mixing coefficient in a ball mill

摘要

Experimental study of the kinetics of mechanosynthesis of TlCl nanoparticles in the reaction 2NaCl + Tl _2SO _4 + zNa _2SO _4 = = (z + 1)Na _2SO _4 + 2TlCl with z = z ~* _1 = z ~* = 11.25 and comparison of kinetic parameters for this reaction with those determined theoretically for the model reaction KBr + TlCl + zKCl = (z + 1)KCl + TlBr with z = z ~* _1 = 13.5 made it possible to estimate the mass transfer (mixing of particles) coefficient in a mechanochemical reactor by the mobile milling tools.
